ATOMIZER. j

To all whom t may concern.'

Be it known .that LIMIARRY A. GrRINE,l a

f citizen of the United States, residing at Los Angeles, in the county of LosA Angeles and Stateof California, have invented a certain new and useful Improvement in Atomizers, of which the following is a specification.

My inventionrelates to a Vliquid hydrov carbon fuel atomizer, or burner, and has for its object to provide means whereby liquid fuels may be discharged in a thoroughly atomized or broken up condition, and particularly whereby; such fuels may be thus discharged into combustion furnaces in connection with the productionv of heat or gas.

The advantage of this atomizer or burner` for. liquid hydrocarbon fuels over those now in vogue consists in the economy secured by a perfect atomization with lowpressure on the steam, air or other `elastic fluid inediiim used in atomizing the liquid hydrocarbon. A pressure of 2O to 25 pounds on the air or steam supply is suflicient when atomizing the very heavy asphaltum base crude oil fuels.

The means for carrying out my invention in a particular form are illustrated in the accompanying drawings, wherein- Figure l is an end view of an atomizer; Fig. 2 a longitudinal vertical section;l Fig. Bis a detail front elevation of the delivery nozzle; Fig. 4L a cross-section Vthrough a modified delivery nozzle, and Fig. 5 a crosssection on the line 5 5 of Fig. l

Like parts are indicated by the same letters in all the gures.

A is a case having the inward projection externally screw-threaded at A2 to engage corresponding screw threads in an aperture in the chamber wall A3 and internally threaded at A4 and provided with the nut A5 whereby it may be screwed into the j threaded -into the case so as to connect with.

the steam'chamber C3.

D is an oil pipe screw-threaded to the case at A, and'D1 is an inner smaller steam pipe screw-threaded at D2 to the diaphragm in Speciication of Letters Patent. i Patented 0(3{3125 1915. Application ied'nnerai, i912. seriaiivovoae.' i. i l

is aiplug consisting of three parts,the Y" chambershell E vand intermediate 'the porv l tion fE? whichfissquarein cross section and' fits the insideof thepipe D'fasindicated in Fig. 5, and is provided with flat sidesElo,

Elbetweenwhch and the inner wallsaof passageways from` said pipe Dto the chamber Eflt ispro vided with the inner passageway E11. The

thepipe D are a series of adjustment for the flow of liquid is made yby screwing the mixing chamber forward or backward on the threaded end of the pipe D. This opening'should` be made as small as possible fora required delivery of Huid so as to cause the fluid to pass around the coniv cal end E7 of the plug E5 in a'thin lm, thus securing a better mixture with the steam, air or yotherelastic fluid atomizing agent.

The delivery nozzle consists of into which leads a passageway F1 tially. The'body is provided with of slots F2, F2 or position, but preferably in such a position as to be swept by the current of fluid as it passes along the inside wall of the nozzle.

Vhile it will be evident from what is shown in my drawings that my invention is an operative device, still changes might be made in size, shape. parts, without departing materially from the spirit of ,my invention, and I wish therefore that my drawings be regarded as in a sense diagrammatic'.

The use and operation of my invention are tangenas follows: Inassembling the parts the mixa body F` a seriesofany desired size, or shape,

ing chamber shell E is-screwed upon the end of the pipe D so that its fluidchamber contains the plug E5 and it is brought toa position where a proper annular'space remains between the plug and the wallof the fluidV chamber. .The projection ,EGA closes the end of the' pipe D1, the innerk passageway*oliu which is therefore connected with the passage E11 in the plug. The middle portion of" the 'plug being irregular in cross section, provides passages connecting the pipe D with the interval between the plug and theA walls of the cavity E8. rlhus the two luids are brought together in a relatively contracted passage or chamber El where they are mixed and where therev is imparted to them a high `Jelocity. I prefer to introduce 'g the steam through the central aperture and oil through the outer annular passageway,-

haveY shown wherein they currentof' mixed-1 fluid passes. tangentially. around or partly aroundV the inside of; the discharge nozzle` past the mouths ot the slots.` As previously suggested, thisV result couldbe accomplished by mechanisms greatly Varying fromv those here illustrated.

The. mix-ingl nozzle may perhapsv more properly be called' a supply nozzle, and this term properly includes the end of the two pipes, thefplugand`- the surrounding portion oli-'the connector, the connector for the two nozzles containing a chamber which may be called the mixing chamber. It is also in fact an accelerating chamber. It connects the two nozzles. f

I claimt:

l. An atomizerhead' comprising a substantially circular drum, a Asupply pipe there-tor projecting tangentially thereinto beyond the center'thereof' and discharging againstthe curved circular wall, aspray discharge, outlet located inisaidf circular wall in the path. ofV the liuidzleaving, the. supply pipe.

2. An atomizer head comprising: a. substantially. circular. drum, a; sup-ply pipe therefor projecting; tangentially thereinto beyond the center thereof andi discharging againstthe curved circular wall, a spray discharge outlet slot, said slot extending transversely across1 the'J path of? the material' lea-ving the' sup-plyl pipe.
